Solar Panel Angle Melbourne

The tilt involves primarily the angle that the panels are facing up into the sky.

Solar panel angle melbourne.

Generally speaking unless your roof is flat the pitch of your home s roof is going to be the angle your solar panels are mounted at. 2 this seems like a reasonable way to maximise solar electricity output but because days are longer in summer it usually helps to tilt them a few degrees lower to take advantage of this. At 90 from true south therefore east and west production can drop to 30. Well it depends based on the orientation and angle of the panels.

Panel angle the optimum panel angle in melbourne is 37 8 the same angle as the latitude of the city. Ideally solar panels would be positioned at an angle of 38 in melbourne equal to the latitude angle of the city 37 81. This solar angle calculator tells you the optimum angle to get the best out of your system. Solar output losses when the panel angle is not ideal.

As indicated in the above diagram an angle of approximately 32 is the best but anywhere between 20 and 40 is optimal for around a 90 efficiency. The optimum tilt angle is calculated by adding 15 degrees to your latitude during winter and subtracting 15 degrees from your latitude during summer. Many federation style houses in inner city melbourne have roof pitches of 45 that are ideal for capturing maximum sunshine during the less productive winter months. The optimum angle varies throughout the year depending on the seasons and your location and this calculator shows the difference in sun height on a month by month.

The summer optimum tilt angle on the other hand will be 34 15 19. The solar radiation that the panels receive is almost the same. In australia common roof pitches are 15 or 22 5 so your modules will most likely be mounted at one of those angles. On a flat roof the tilt is 0 whereas if the angles were to be facing a wall it would be 90.

For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49. Solar panels tilted at an angle equal to the latitude will face exactly midway between the sun s highest point in the sky in summer and its lowest point in winter. The table below features a solar panel angle by zip code for at least one city from every state. However if the panels are turned at an angle greater than 45 compared to true south production begins to decrease significantly.
